CORPORATION OF MAINE.

Specification of Letters Patent.

Patented May 8, 1906.

Application filed September 24, 1900. Serial No. 30,913.

T at whom it may concern..-

Be it known that 1, ROBERT R. THOMP- SON, a citizen of the United States of America, residing at Chicago, in the county, of Cook and State of Illinois, have invented certain new and useful Improvements in Mattress- Tufting Machines, of which the following is a specification.

My invention relates to certain improvements in tufting-machines, the machine to which the invention has been particularly applied being a machine for tufting mattresses, and the object of the invention being to construct a machine which shall, by means of a single reciprocating movement of the operating parts, place the tufts upon both sides of the mattress, perforate the same, pass the twine through both tufts, and tie it to fasten the tufts together and confine the mattress between them.

It is a further object of the invention to make various minor and subordinate improvements in the mechanism and -manner of arrangement of the various devices used therein.

To these ends the invention consists in certain novel mechanism, the specific details of which will be described at length below, and the essential features of which will be pointed out in the appended claims.

In the drawings, Figure 1 is a planview of the machine with a part of the tracks broken away to permit the view to be as large as possible upon the sheet. F ig. 2 is a view partly in side elevation and partly in vertical crosssection, the line of section being taken at 2 2 of Fig. 1, and the view being in the direction of the arrow 2 in said figure. Fi 3 is an enlarged side view of the upper an lower compressor-heads. Fig. 4 is a front view of the parts shown in Fi 3 ,the view being in the direction indicate by the arrow 4 in Fig. 3. Fig. 5 is a central vertical section of the upper compressor-head, the line of section being taken at 5 5 in Figs. 1 and 4 and looking in the direction of the arrow 5. Fig. 6 1s a view similar to Fig. 5, but showlng the tube for rotating the knotter in side elevation, and the operating parts of the machine in a pos1- tion at which the compressors havereached their limit of compression.
